Perhaps a bit off-beam for this list, but called to mind are skaldic and eddic kennings that refer to the ocean or water bodies, such as these examples of modern renderings of such terms found in Beowulf (Seamus Heaney's most recent translation included): whale-road, whale-path, whalepaths, whale's road, whale's path, whale road; swan-road, swan's road, swan's path, swan's course, swan's riding; waveswells; seabird's bath, gannet's bath, etc.
